fantasy books that aren’t super romance heavy or contain juvenile characters/ relationships?

Basically what the title says. I want to get back into reading fantasy but I am unsure of what to choose because most popular fantasy books seem to be YA. I’m not completely against YA but I hate when the characters are super immature and have very juvenile relationships with one another. I am also not a huge romance person. If romance a minor subplot then it’s totally fine but when a large portion of the story revolves around romance or the forbidden love cliche then I get bored. Any suggestions for me? Thank you!!
